CHAIR.

T 0 all whom t may concern.:

Be it known that I', HOWARD G. VVRrGHfr, a citizen of the United States,residing at Bon Air, in the county oit Chesterfield and State ofVirginia, have invented certain new and useful Improvements in Chairs,of which the following is a specification.

This invention relates to certain new and useful improvements in chairsand it more particularly relates to the class or' chairs pro vided withbacks, such as are used in theaters and other public places otamusement.

One of the objects of my invention is to provide the seat to such chairsas above set forth with means to raise the seat consisting of a spiralspring, one end of which surrounds and is attached to a bracket eX-tending from the side standard of the chair at a point below the seat.The other end of the spring is elongated and presses against the bottomof the seat so that when such seat is unoccupied, the pressure of thespring automatically causes it to turn through an are of about degreesand to rest in a position substantially parallel to and against the backof the chair.

Another object of my invention is to so construct the device as to bringabout economy of material used in each devire and economy of laborrequired to attach the devices to a row of chairs, the constructionbeine' such as to operate a seat to the left as werll as to the right ofthe side standard to which it is attached, so that instead of applying adevice to each side standard. of a chair, it is necessary to apply oneonly to each alternate side standard; in otherwords,

to but one half the number of chairs in lace.

With these and other objects in view which may be incident to myimprovements, the invention consists in the parts and cont binations tobe hereinafter set t'orth and claimed, with the understanding that the iseveral necessary elements comprising my L invention, may be varied inconstruction,

proportions and arrangement, without departing from the spirit and scopeof the appended claims.

In order to make my invention more clearly understood, I have shown inthe accompanying drawings means for carrying the same into practicaleffect, without limiting the improvements in their useful appli- @ationsto the particular constructions, which for the purpose of explanation,have been made the subject of illustration.

In the drawings:

Figure 1 is a side elevation of the chair showing the seat lowered.

Figure 2 is a similar view showing the 60 seat raised.

Figure 3 is a sectional view along the line 3f-3 oi Figure 2, showing myimproved device attached to the side standards of a chair.

Figure l is a sectional view on the line .4t-4 of Figure 3, showing thefront and rear standards of thel chair and the bracket to which thespring seat lifting arms is attached.

Figure 5 is a detail view showing the lower end of the bracket attachedto the side standard of the chair in a modified manner.

The numeral l refers to the side frames or standards of a chair the samebeing provided with feet 2 east integrally therewith and providedwithapertures through which are inserted bolts or screws 3 by means ofwhich the chair is firmly secured to the floor. Said standards areconnected to- 8o gether in the rear by a back attached to each sidemember, and by a side brace 4 riveted or otherwise secured to the frontand rear side standards by bolts 5. The numeral 6 represents a yokeformed of a single piece of metal which is bent in the Jform moreclearly shown in Figure 4 so as to readily embrace both the front andrear standards to which it is securely bound by means of a bolt 7. Aset-screw or bolt 8 is provided 90 at the bend 8 of the yoke 6 wherebyit can be more closely and readily adjusted and held in place. When thechairs areY located upon a gently rising floor, as is usually the casein that part of an auditorium designated the orchestra chairs, thissetscrew is placed so as to be operated against the rear standard. When,however, the chairs are otherwise placed, such for insta-nce, as in thegallery of a theatre, it would. be impractical to operate said set-screwor bolt 'from the rear position and in that case the yoke is reversed sothat the set-screw is operated against the front standard instead of therear standard.

Each member 4 is provided on each side at or near its center with anoutstanding bent portion or boss 9 which is apertured for the receptionof a screw or bolt 10, the purpose of which is to pivotally support asuitable arm 11 the upper member 12 of which is provided with aperturedHanges 13 to which the seat is secured by screws or otherwise.

Below 'the boss 9 are brackets 14. The lower portion of each bracket isturned upon itself in such a manner as to embrace one of the sidemembers 15 of the yoke 6 to which it is secured by bolts 16. Just above(the point of) the bolt and at a point 17 the bracket is turned at anangle of about degrees for a short distance and at 18 is again turned ata reverse angle so as to form a straight member 19 which extendsparallel to the side standard, and to said member 19 there is attached ascrew-threaded bar or bolt 2O around which is coiled a spiral spring 21.One end 22 of said spring abuts against lthe straight member 19 and theother end is elongated in a straight line to form the member 23, thegreater portion of which contacts with the bottom of the seat 24. At theend of the spiral spring opposite the member 19 the bolt 2O is providedwith a washer 25 which abuts against the head of the bolt and tends tohold the spring in its proper place.

The modification shown in Figure 5 is intended to show another manner ofsecuring the brac-kets to the side standard. The figure shows an absenceof the fastening bolts 16 and it is the intention sometimes to securethe brackets to the side standard by spot-welding rather than by bolts.

It will be observed while the operation of each seat is distinct andseparate from the operation of the adjacent seat, there is decidedeconomy in being able to so manufacture the device that it will servetwo chairs, and a further economy lies in the reduced amount of laborrequired in placing it in position upon each alternate chair instead ofevery chair.

Upon inspection of the drawings it will be obvious that with my improvedform of seat there is nothing to prevent a hat support from being placedthereunder, and that the chair may be manufactured and sold `with orwithout such support, in accordance with the wishes and order of thecustomer.

l/Vhile I have shown and described the preferred embodiment of myinvention, I wish it to be understood that I do not conne myself to theprecise details of construction herein set forth, by way ofillustration, as it is apparent that many changes and variations may bemade therein, by those skilled in the art, without departing from thespirit of the invention, or exceeding the scope of the appended claims.

I claim:

1. A device of the character described comprising a yoke adapted to beapplied to the side standards of a chair below the seat pivot, bracketsextending outwardly and upwardly from opposite sides of the yoke andinto the seat axis, a spring mounted on each bracket to contact with aseat to the right and to the left respectively of the yoke, toautomatically tilt said respective seats when unoccupied.

2. A device of the character described comprising a split ring yoke toembrace the side standards of a chair, means to solidly lock said yoketo the side standards, an upstanding bracket on said yoke, and a spring,one end of said spring contacting with the seat on the standards toautomatically tilt the seat when unoccupied, the other end of the springsecured to the said bracket.

In testimony whereo-f I aflix my signature.

HOWARD G. WRIGHT.
